Obesity and type 2 diabetes are two of the most significant health challenges of our time. With the increasing prevalence of these conditions, medications that target both weight loss and blood sugar management have gained global attention. Among them, Wegovy and Ozempic stand out as leading options.
The Drugs
These two drugs, both belonging to the class of GLP-1 receptor agonists, are often compared due to their shared active ingredient—semaglutide. However, their uses, dosages, side effects, and approvals differ. This article provides a comprehensive comparison of Wegovy vs Ozempic, explaining their similarities, differences, benefits, risks, and cost considerations.
